OneDrive File Size Limit?
This page uses the verified OneDrive website-upload profile for a modern browser. Sync, Office save, SharePoint, older browsers, work or school contexts, and storage availability can require different evidence.
The verified profile represents the modern-browser OneDrive website path. Do not apply it blindly to Office save, sync-client, SharePoint, or another workflow with different conditions.
Do not change the original file just to test a guess. Pick the closest situation and move to the matching ARADURU check.
Use this profile only for the modern-browser OneDrive website upload context it describes. Storage and account restrictions can still block a file that passes the represented size rule.
Use the file that actually failed
Start with the same file so the result reflects the real failure, not a substitute file.
What happened when you tried to upload?
You upload through onedrive.com
The modern-browser website profile is the closest represented context.
The error comes from Office or sync
Do not force that workflow into the website-upload rule.
The file passes but still fails
Check storage, sign-in, permissions, browser, network, or the exact OneDrive message next.
A practical order before you retry
Confirm that the failed path is the OneDrive website in a modern browser.
Compare the selected file with the verified per-file website rule.
Keep Office save, sync-client, SharePoint, older-browser, storage, and account conditions separate.
When the represented rule passes, troubleshoot the exact OneDrive surface rather than compressing by default.
OneDrive limits are meaningful only when the upload surface matches
A size result for the website path should not be used as a diagnosis for every OneDrive-related workflow. Confirm the surface and then follow the exact account, storage, transport, or error evidence.
